To all whom t may concern.'

Be it known that l, ARQUIMEDES CAPITAN, citizen of the Republic of Chile7 residing at Bavid, in the Province of Chiriqu and Rcpublic of Panama, Canal Zone, have invented certain new and useful improvements in Train-Signals; and l do hereby declare the following to be a full7 clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in train signals and the principal object of the invention is to provide a positive action signal which is operable within the cab of the locomotive so as to insure the engineer getting the proper signal.

Another object of the invention is to provide a device which is adapted to be controlled by the semaphore signal to cut in an electric circuit so as to set a bell or other alarm device to ringing.

Still another object of the invention is to provide a device which may be readily attached to a 'locomotive of the ordinary construction without in any way changing the same.

With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specilioation and accompanying drawings, in which Figure 1 illustrates the circuit closer for a signaling device constructed in accordance with this invention and Fig. 2 is an enlarged fragmentary sectional viewfof a portion of Fig. 1 illustrating a modified form of the device.

Referring to the drawing the numeral 1 designates the side wall of the cab of a locomotive having secured thereto a supporting bracket 2. This supporting bracket is provided near its outer end with a standard 3 which is preferably hexagonal in cross section and slidably mounted on said standard is a sleeve 4 carrying the arm 5. This arm 5 is formed at its rear end with a suitable contact 6 and the outer end of the arm carries a screw eye 7 the use of which will appear as the description proceeds.

The upper end of the standard 8 is provided with a head 8 having secured thereto lin any suitable manner a standard 9 provided at its upper end with an arm 10 which extends outwardly at right angles thereto and is provided at its outer end with a screw eye 11. AA suitable flexible connection 12 of cord, wire or any other suitable material is normally stitched between the screw eyes 7 and 11 to hold the arm 5 in its elevated position as illustrated in fold lines in the drawmg.

The contact 6 is connected by a suitable wire -13 to one pole of an electric bell 14, the opposite terminal of said bell is connected by a wire 15 to the battery 16 the opposite terminal of which is connected by a wire 17 to the stationary contact 18 carried by the side 1 of the locomotive. The contact 6 when the arm 5 moves downwardly is adapted to engage the contact 18, it will thus be seen that the circuit will be closed between the bell and the battery thereby setting said bell in operation and warning the engineer of approaching danger.

In order to break the flexible member 12 the semaphore arm designated by the numeral 19 is provided with a. suitable knife designated generally 20 comprising a body 21 having a blade 22 extending longitudinally therefrom and this lmife is adapted to cut the flexible member 12 when the semaphore arm is in signaling position so as to permit the arm 5 to drop and complete the circuit through the bell 14.

Tt will be understood that any other suitab e the bell 14v and that the device may be readily applied to any suitable type of signal and locomotive without in any way departing from the spirit and scope of the invention. In the modified construction of circuit closer reference will be had particularly to Fig. 2, in which the lower arm is designated 5a and is carried on the sleeve 4a which is slidably mounted on the stud 3a. A suitable bolt 23 is slidably mounted in the sleeve and is nor mally urged outwardly by the compression coil spring 24. This bolt is adapted to engage in a recess in the stud 3a near its upper end so as to hold the sleeve and arm 4a and 5a respectively raised. As illustrated it will be seen that the bolt normally tends to move outwardly under the influence of the spring 24 but is held against outward movement when the device is in non-signaling position by the flexible connection 12a which corresponds to the flexible member 12 previously referred to.

ln the operation of the modified form it will be seen that when the flexible member 12a is severed, the spring will force the bolt signaling means may be substituted for 23 out of engagement With the Walls of the recess in the stud 3 thereby permitting the arm 5 to fall thus completing the ciroult.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood vthat such changes may be made in the combination and arrangement of parts as Will secured to the upper end of the standard, a parallel arm slidable on the standard, a con- 15 tact carried by the parallel arm, a stationary vContact and readily destructible means for holding the slidable arm upwardly and the contacts away from each other.

In testimony whereof I aiix my signature 20 in presence-0f tWo Witnesses.
